The other teens also suffered burns, but their injuries were minor and did not require medical treatment, according to River Vale police Lt. John DeVoe.

“The solution contained a mixture of chemically available hand-sanitizers,” Devoe said Tuesday. “Four juveniles used the same bottle. There was some kind of reaction that was created (by mixing the chemicals.)"

Devoe said officers went to the store shortly after 8 p.m. Monday and seized eight bottles of the solution – which had already been removed from shelves – and one empty bottle. They also took the components used in the mix, Devoe said.

Police believe there are 10 more bottles of solution out there and they’ve warned people against using the solution.

The sanitizer seized by police is being tested, but Devoe said store employees told them what was in the bottles and the police say they don’t have any reason to doubt them.

Devoe added that he does not believe store workers intended to hurt anyone. “In my opinion it was a complete lapse in judgement,” he said.

A woman who answered the phone at the store early Tuesday said the sanitizer is safe but declined to comment further.

Investigators became aware of the incident through social media, Devoe said. One parent had posted photos of her son’s burns on Facebook but took them down Tuesday, hired a lawyer and was declining to speak with reporters, Devoe said.

Devoe said the matter remains under investigation and that the incident was reported to county and state officials.

Anyone who bought the spray from the River Vale 7-Eleven is asked to call police at 201-664-1111.”
